the wire to the park brake lite just unplugs, I`m trying to picture the 71 Park brake cable hook up it changed between 70 -71 & I have worked on both in the last 2 months but can`t remeber which is which , I remeber 70 being tpougher to work on though
The harness can be adapted to the ralley dash , the ralley has the wires going separatly to the individual gauges & hook ups , the std dash uses a gang plug so you would have to get the correct ends & solder them onto the individuaol wires to hook up the ralley dash
